How to decide "time at the end of load step" for a transient analysis.?
I'm carrying out an electromagnetic transient analysis in ANSYS APDL and enable to decide a specific time for the analysis . As I'm getting different result for different time, by which it has become difficult to decide which result is correct.
The analysis is - a copper sleeve is rotating at 188 RPS (Hz) and a Halbach magnet is held stationary opposite of copper sleeve (see fig.). In this problem I'm calculating Lorentz force associated with copper plate through transient analysis. But everytime I get different result for different time. Is there any criteria to decide the "time at the end of load step" for a transient analysis.?
Please provide the guidance for the same.
